FUSE SELECTION GUIDE

The fuse must carry the normal load current of the circuit
without nuisance openings.However,when an over current
occurs the fuse must interrupt the over current,limit the energy
let-through,and withstand the voltage across the fuse during
acting.To properly select a fuse the followings must be
considered:
(1)Normal operating current(The current rating of a fuse is
typically derated 25% for operation at 25% to avoid nuisance
blowing.For example,a fuse with 10A current rating is not
usually recommended for operation at more than 7.5A in a
25% derating.)
(2)Overload current and melting time of the fuse.
(3)Application volage(AC or DC voltage).
(4)Inrush currents,surge currents,pulses,start-up currents
characteristics.
(5)Ambient temperature.
(6)Applicable standards agency required,such as UL,CSA,
TUV,VDE,PSE and IEC....
Considerations: Reduce installed cost,ease of removal,
(7)mounting type/form factor,etc.
